I don't have a pdf up yet, but I wanted to post this that I have dipped my toes just a little into Dark Sun. I do have a system for Defiling and Preserving also in the work, but the racial templates took up so much space I decided to do separate posts.

Besides the races of Dark Sun, the main component of Dark Sun that I felt needed a post was the way magic works due to its departure from the usual well spells are cast in fantastical worlds. A lot of other concepts from Dark Sun such as heat, thirst, and the process of killing stuff are quite well covered in the core book, but I'm always open to suggestions of what you'd like to see.
